Butyrka prison

Butyrskaya prison (Russian: Бутырская тюрьма, romanized: Butýrskaya tyurmá), colloquially known simply as Butyrka (Russian: Бутырка, IPA:), is a prison in the Tverskoy District of central Moscow, Russia. In Imperial Russia it served as the central transit prison. Now it is a pretrial detention facility (remand prison).

During the Soviet Union era (1917–1991) it held many political prisoners. As of 2022 Butyrka remains the largest of Moscow's remand prisons. Overcrowding is an ongoing problem.
